HP Visualize X-Class were Intel-based personal workstations for Windows NT, released in 1999. With the Pentium III-based X-Class, HP complemented its expensive PA-RISC workstations for entry-level technical design.
X-Class X500 to X550 (model A5014A) were high-performance HP NT workstations, above similar, but lower-tier Visualize P-Class.

Based on Intel Pentium III processors and up to two-way SMP capable with Intel 440GX chipset, X-Class used modern 32-bit Xeon CPUs in contrast to Katmai/Coppermine and BX P-Class.
HP Visualize X-Class were dedicated professional graphics workstations for 3D design, CAD and CAM on Windows NT, used for professional digital content creation.

Visualize X-Class shared almost nothing with the PA-RISC based Visualize brethren but the Visualize graphics adapters, which they use in modified + Versions on AGP. They also were shipped with 3rd-party graphics such as Elsa Gloria Synergy.
The dark-grey mini-tower HP X-Class used was similar to PA-RISC HP Visualize B1000, C3000, C3600, C3700 workstations and slightly different to P-Class.
- HP Visualize X500, A5014A, were introduced in 1999
- HP Visualize X500, A5014A, with dual-CPU, 512 MB RAM and Visualize fx6 cost $12,326
- HP Visualize X550, A5014A, were introduced in 1999 for $5,906
The later different Visualize x-class workstations were released soon after, based on Pentium III Xeon processors with RCC chipset, HP models A1280A and A1280B.
System architecture
Processors
X500 and X550 use Pentium III Xeon processors with 512 KB or 1 MB L2 cache on full-frequency. CPUs are installed in SEC cartridges in two Slot 2 slots.
System | CPU | Speed | L1 Cache | L2 Cache* |
---|---|---|---|---|
X500 | 1-2 Intel Pentium III | 500 MHz | 32 KB on-chip | 0.5-1.0 MB on-package |
X550 | 1-2 Intel Pentium III | 550 MHz | 32 KB on-chip | 512 KB back-side on-package |

The LCD panel on front of the case shows BIOS and configuration info and errors by the BIOS, enhanced by beeps. The LCD can also be used for diagnostics.
Benchmarks
No official SPECint or fp results could be found for HP Visualize X-Class, so a similar Dell workstation 610 with GX chipset is taken as reference.
